FERTILIZER-DISTRIBUTER.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed October 20, 1910, Serial No. 588,063. Renewed June 6, 1918. Serial No. 238,608.

To all whom it may concern:

Be it known that I, FRED GINKEL, of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Fertilizer-Distributer, of which the following is a specification.

My invention relates to fertilizer distributers and has for its object means whereby the comb may be positioned to act as an end board; and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a longitudinal sectional view of a fertilizer distributer embodying my invention, parts being removed.

Fig. 2 is an enlarged elevation of the rear portion of a fertilizer distributer, the beater being indicated in dotted lines, and the position of the comb when in its position to coact with the beater being indicated in dotted lines.

1 is the body or box of the fertilizer distributer; 2 is the movable bottom or apron consisting of sections carried by a chain 3 which is movable over sprocket wheels at and 5 located respectively at the front and the rear of the box 1; 6 is the beater. The bottom i actuated from the rear axle 7 in any well known manner and may be connected to and disconnected from its actuating means, at will, in any well known man ner, as will be understood by those skilled in the art. The beater 6 is usually a rotatable beater and is actuated from the axle and its operation is controlled in synchrony with the bottom in any well known manner as will be understood by those skilled in the art. All of the foregoing parts may be of any desirable form, size, and construction.

8 is a comb or rake which is supported by freely movable holding and guiding devices arranged to normally support the rake crosswise of the body in front of the beater and yieldingly hold the same against the rear end portion of the load and movable by the pressure of the load on the comb or rake during the rearward movement of the load by the movable bottom or apron to carry the comb or rake into a position above the beater. This guiding and holding means includes a part for engaging the rake and maintaining the rake with its teeth in substantially upright position in all positions of the holding and guiding means. As here illustrated, the comb or rake 8 includes a back or cross rail and tines or fingers 9 depending therefrom, the comb being supported by suitable means by which it nor mally occupies a position to act as an end board as indicated in Fig. l, and in full lines in Fig. 2, the supporting means being movable during the initial movement of the bottom to carry the comb into a position above the beater 6 to perform its ordinary I functions, as indicated in dotted lines in Fig. 2. The movement of the comb from the position in which it acts as an end board to the position in which it performs its usual functions as a comb, is effected by the pressure of the load when the bottom is be ing actuated, and when such pressure is removed as when the load is exhausted, the combfa-lls by its own weight from the position shown in dotted lines, Fig. 2, to that indicated in full lines.

The supporting means comprises two pairs of links located respectively on opposite sides of the body 1 of the fertilizer distributer and connected to opposite ends of the comb, the members 10, 11 of each pair being pivoted respectively at 12, 13 to the body at fixed points spaced apart and normally extending in substantial parallelism upwardly and forwardly and being pivoted at l4, 15 to the opposite ends of a link 16 which connects their upper ends. This connecting link is pivoted to the comb 8 and as shown, the comb 8 is formed with forwardly extending brackets as 17, each bracket 17 being pivoted at 18 to one of the links 16, the pivot 18 being alined with, and usually an extension, of the pivot 14. The pivotal movement of the comb is about the single axis 18 and is limited by an adjustable shoulder as a screw 19 threading through a lug 20 on the outer face of each bracket 17, the shoulder 19 coacting with the upper edge of the link 16, thus limiting the pivotal movement of the comb in one direction. The comb is yieldingly held from movement in the opposite direction on its pivot by a spring 21 connected at one end at 22 to the rear end of each bracket 17 eccentric to the axis of the comb and at its opposite end at :23 to one of the links 10, 11 here shown as link 11, this spring yieldingly restraining pivotal movement of the comb but allowing the same to yield su'liiciently to prevent breakage of the comb when large lumps of fertilizer are being carried by the beater against the comb.

The comb is limited in its movement when it assumes either of its operative positions by a stop 2% supported by the body of the fertilizer distributer and located between the lower ends of the links 10, 11 of each pair, this stop having engaging faces 25, 26 arranged at an angle to each other for engaging respectively opposite edges of the links 10, 11, the face 26 engaging the link 11 when the parts are in their position indi cated in full lines, Fig. 2, and the face 25 engaging the link 10 when the parts are in their position indicated in dotted lines, Fig. 2.

The pivots 12, 13 at the lower ends of each pair of links 10, 11 are reinforced in their support by a brace 27 connecting said pivots.

Owing to the arrangement of the links 10, 11 and 16, the angle of the comb remains the same during its movement from one operative position to the other and when the comb is in position to act as an end board, the pivot 15 is arranged slightly above a straight line intersecting the pivots 13, 14 so that the comb is not locked in such position and also is not moved too easily out of such position.

In fertilizer distributers heretofore in use, the end board has been removed and inserted by hand or the beater has been constructed to shift toward the load to act as an end board and from the rear end of the load in order to obtain sufficient clearance to start rotating. By my invention the comb is arranged to move automatically into position to act as an end board and also to move automatically and by a translatory movement into and out of its position near the beater. It will be understood that throughout this specification and claims, the word comb is used merely for convenience and that applicant does not limit himself to the comb shown in the drawing and that any device movable by the movement of the bottom to act as an end board may be employed.

What I claim is 1. In a fertilizer distributer, the combination with a body, a movable apron, and a beater, of a rake, freely movable holding and guiding devices therefor arranged to normally support the rake crosswise of the body in front of the beater and yieldingly hold the same against the rear end portion of the load and movable by the pressure of the load on the rake during the rearward movement of the load by the apron to carry the rake into a position above the beater, substantially as and for th purpose de scribed.

In a fertilizer distributer, the combination with a body, a movable apron, and a movable beater, of a rake, and freely movable holding and guiding means therefor arranged to press the rake forwardly against the rear end portion of the load and to move rearwardly and upwardly to carry the rake above the beater under pressure of the load when being carried rearwardly by the apron, the rake being pivoted to said means, and said guiding and holding means including a part engaging the rake, and maintaining the rake with its teeth in substantially upright position in all positions of the holding and guiding means, substantially as and for the purpose specified.

3. In a fertilizer distributor, the combination with a sec y, a movable apron, and a beater, of a rake, a freely movable arm pivoted to the body and pivotally connected to th rake, the arm inclining forwardly and upwardly from the pivot connecting it to the body, and a part carrying the rake and being pivotally connected to the upper end of said rm, means for limiting the movement of the arm in a forward direction before it reaches a horizontal plane and limiting the movement of the arm rearwardly before it reaches a vertical plane whereby said arm is moved rearwardly by the pressure of the traveling load against the rake and forwardly against the load as the pressure on the rake varies.
